摘　　要：采用重铬酸钾-硫酸氧化法测定全碳含量,对贵阳二环林带11个主要造林树种的碳净贮量、分配格局及其未来10年各树种的碳净贮量和固碳量的经济效益作了初步研究。结果表明,碳净贮量从大到小依次为紫薇(5301.45 kg/hm2)>黄皮树>杜仲>香樟>杜英>猴樟>银杏>南酸枣>刺槐>栾树>大叶女贞(581.85 kg/hm2)。各器官碳净贮量中,主干占比例最大,枝、叶、根比例接近。预计10年后11个主要造林树种的碳净贮量可达602.85 t/hm2,经济价值可达183 869.25元/hm2。The total carbon were evaluated by methods of potassium dichromate and sulphuric oxidation.The net carbon storage now and 10 years later and spatial distribution of carbon were studied in 11 artificial tree species on the second forest zone around Guiyang city, The results showed that the net carbon storage of 11 tree species were decreased with the order： 5 301.45 kg/hm^2 in Lagerstrcemia indica, 2 775.05 kg/hm^2 in PheUodendron chinense Schneid., 2 707.47 kg/hm^2 in Eucommia ulmoides, 1 666.78 kg/hm^2 in Cinamomum camphora, 1 322.5 kg/hm^2 in Elaeocarpus decipiens, 1 120.49 kg/hm^2 in Cinnamomum bodinieri Levi., 882.95 kg/hm^2 in Ginkgo biloba L., 720.5 kg/hm^2 in Choerospondias axiUaris, 713.46 kg/hm^2 in Robiniapseudoacacia, 591.49 kg/hm^2 in Koelrenteria Paniculata, 581.85 kg/hm^2 in Ligustrum lucidum. The percent of net carbon storage of stem in each tree were higher than other organs, and which in branch, in leaf and in root were approximate. The net carbon storage of 11 tree species would amount to 602.85 t/hm^210 years later, and the economic value will amount to 183 869.25 yuan/hm^2.
